..ask Geohot? He'll fix you up. Just scramble around until Sony panics and removes the blu-ray player capability, or something like that - he'll get you a custom firmware..
No, it works by "detecting" unheard audio signals in a stream. So the drm isn't checking some database on the net, or anything like that - it just checks for the embedded cinavia sounds.
So.. basically, the way to circumvent it is to not use:
2. rips from discs intended for pre-screening.
3. never buy anything that use cinavia drm, and send dead horse's heads to any publisher who will make movies you buy have the scheme.
as well as..
4. sell your ps3 when that happens, and you cannot copy your own dvds any more.
..on the other hand, you could just.. not burn the thing to a dvd, and just watch it from the rip, I guess.
Even so - Sony can go screw themselves. You know what this drm is intended to control? Their own paid folks in Q&A who push the movies out on torrents before the release date. And who pays for this drm? The DRM that prevents you from using your ps3 as you expect any other player to work? We do. And the result is: I use something else for playback, just to make sure I'm not going to get one of my own copies, or something I borrow from a friend, suddenly not working on me.
So loss for Sony, and loss for Sony.
Incidentally - where is the Kurozuka blu-ray I wanted to buy? Nowhere. It's not getting released after all. So where do you think I will get this? Take a guess.
